Subject: [PATCH net-next 01/13] net: stmmac: selftests: Return proper error code to userspace
Date: Mon,  2 Sep 2019 10:01:43 +0200	[thread overview]
Message-ID: <04cd49b1c7529a464fe0b03a88b275ce85b1ca3d.1567410970.git.joabreu@synopsys.com> (raw)
In-Reply-To: <cover.1567410970.git.joabreu@synopsys.com>
In-Reply-To: <cover.1567410970.git.joabreu@synopsys.com>

We can do better than just return 1 to userspace. Lets return a proper
Linux error code.
